Abstract: Human skin has tactile receptors that have different response characteristics. These characteristics are effective for the tactile texture classification. In this paper, we propose a classification method by using a magnetic tactile sensor. The tactile sensor has two sensing elements that detects slow and fast deformations occurred on the surface of itself. We confirm that the output voltages of the sensing elements include frequency characteristics of tactile texture. In addition, a support vector machine classifies tactile textures based on the output voltages.
